The Southern Pride model DH-65 smoker oven is an all- electric unit requiring a 120/208 or 120/220 volt, single phase 30-amp circuit. The oven consists of a 208 or a 240- volt, 4500 Watt main heating element, a 120 volt 300 watt smoke element, a 120 volt 750 watt steam element, and a 120-volt convection fan motor. Cook times and temperature. are controlled by digital control system.

The DH-65 menu uses a two stage cooking cycle. In Stage 1 the main heating element, smoker, steamer and convection fan are all on. This creates a high heat and sear with smoke to lock in the flavor of the ribs. The control will maintain the set point temperature programmed in stage one for the time programmed. Then in stage 2 using the steamer, smoker, and convection fan, tenderizes the ribs by cooking them lower and slower and using steam to keep them moist an make them fall-off-the-bone tender when they are done. When the stage 2 menu is over the oven sounds an audible alarm to let you know that the cycle is finished.

The digital control system consists of a digital controller, a 120 to 24 volt, step-down transformer (to power the controller), a 40-amp (main heating element), a 25-amp (steam element), and two-10amp solid state relays (convection fan, smoker). To prevent over heating a 340- degree hi-limit thermostat and a contactor is also used in the circuit between the 40-amp solid state relay and the heating element.

120 volt current from the black and white wires of the terminal block is sent to the transformer, to the convection fan solid state relay, the smoke element solid state relay and the steam element solid state relay. 208/240 volts from the terminal block, black wire is sent to the contactor, and the red wire is connected directly to one wire of the main heating element.

Once the cooking menu has been selected and the START touch pad has been depressed, the digital control sends 5 volts DC to the convection fan, the heating element, the steam element, and the smoke element solid state relays. Also 120 volts from the # 1 terminal of the fan relay is sent thru the hi-limit thermostat to the contactor coil terminal. The purpose of the contactor is to prevent the oven from over heating in the event the 40amp solid state relay fails to break the circuit, the hi-limit thermostat will open at 340 degrees cutting off current to the coil of the contactor this will open the contactor cutting off power to the main heating element.

The Southern Pride, model SC-200-SM smoker oven is an all-electric unit, requiring a 120/208 or a 120/240-volt 4 wire single-phase 30-amp circuit. The unit consists of a 208 or 240-volt main heating element a 110/120-volt smoker element, a hi-limit thermostat, a contactor, and a 110/120-volt convection fan motor. There is also an option for a second smoker box and element.

The SC-200 has a digital control system. The digital control panel consists of six button touch pad to set a menu, select the desired cook temperature, cook time, hold time, and smoke ON or OFF.

DIGITAL CONTROL SYSTEM (on all current models)

The digital system consists of a digital controller, a 110/120 volt to 24 volt step-down transformer, two 10 amp and one 40 amp solid state relays. A menu can be programmed with a cook time, cook temp, a hold time and a hold temperature, or the hold can be turned off and the smoker can also be turned off or on. Once the oven heats up to near set temperature the controller will pulse the current to the heating element to maintain the set temperature.

Once the time, temperature and hold on or off have been selected press Start/Stop, the control will ask for wood chips - press up button for smoke down button for no smoke. A 5- volt DC current is sent to the 40-amp relay, the smoker relay (if selected) and to the fan relay. The fan relay sends 110/120 volts to the fan motor and thru the hi-limit to the coil connection of the contactor. When the oven heats up to within a few degrees of set temperature the controller will pulse the heating element current. The smoke element will stay on for four hours and shut off or shut off when the cook cycle ends if less than four hours. When the cook cycle is completed the oven will shut off and sound an audible alarm or go into a hold cycle, depending on how the menu was programmed at the beginning of the cook cycle. With the technology of the digital controls the oven will maintain the set point temperature to within a few degrees.

Why is my SC-200 oven overheating above 340 degrees no matter what temp. it is set at?

It is Possible that the 40 amp Solid State Relay that controls the power to the main element is stuck in the closed position.

The 40 amp solid state relay is controlled by a 5 volt DC current from the digital controller to the # 3 and # 4 terminals on the relay. This 5 volt current closes the circuit between #1 and #2 terminals allowing current to flow to the main heating element. When the oven heats up to near the temperature setting, the controller begins pulse the 5 volts to the relay. This also pulses the current thru #1 and # 2 to the element allowing the oven to maintain a more even cooking temperature. If the relay fails in the closed position current cannot be cutoff to the element causing it to continue heating until the hi-limit opens at about 340 degrees cutting off coil voltage to the contactor. This will open the circuit to the heating element until the oven cools down.

DIGITAL CONTROL SYSTEM

The digital control system consists of a digital controller, a 110 to 24 volt step-down transformer, a 40-amp, a 25-amp, and two-10amp solid state relays. To prevent over heating a 340- degree hi-limit thermostat and a contactor is also used in the circuit between the 40-amp solid state relay and the heating element.

110 volt current from the black and white wires of the terminal block is sent to the transformer, to the fan solid state relay, the smoke element solid state relay and the steam element solid state relay. 208/240 volts from the terminal block black wire is sent to the contactor and the red wire is connected directly to the other wire of the main heating element.

Once the cooking menu has been selected and the START touch pad has been depressed, the digital control sends 5 volts DC to the convection fan, the heating element, the steam element, and the smoke element solid state relays. Also 110 volts from the # 1 terminal of the fan relay is sent thru the hi-limit thermostat to the contactor coil terminal.

In the event the oven temperature exceeds the maximum limit of about 340 degrees, the hi-limit thermostat will open, this will cut off the 110 volts to the contactor coil breaking the current to the heating element until the oven cools down.
